Job description

$9M+ ARR, 10,000+ customers. In under 12 months.

We build AI voice agents for small and medium-sized businesses so they never miss a call again and can focus on the work they actually love.

Our AI handles every call automatically. But voice is just the beginning. Our vision: to become the fully automated AI suite for SMBs.

We live ownership. You’re end-to-end responsible for your projects and tasks. No politics, few meetings, direct feedback. At fonio you build alongside the smartest and most ambitious people in the scene.

Become part of one of the fastest-growing startups in Europe!

Your role

You own how fonio feels on the web. Our website is our most important storefront — and right now it’s not where it needs to be. You don’t build one nice page, you build a system: a design system and landing page templates that roll out into localized pages across 9+ markets. Continuous optimization, not a one-off redesign. You design and ship - you own the build end-to-end, not a handoff to engineering. We’re building an AI operating system for SMBs - people should feel that on the website.

What to expect

• You own the design and continuous optimization of our website and landing pages

• You build a scalable design system with reusable components

• You develop landing page templates that localize across all markets (DACH, FR, IT, ES, UK, PL, US, and more)

• You design and ship live yourself - full ownership from concept to published page

• You think in user journey, conversion, and responsive design

• You work closely with the Creative Director on brand direction

Who we’re looking for

• Several years of experience as a UI/UX or web designer focused on converting websites (portfolio required)

• You think in systems and components, not individual pages

• You build and ship yourself

• Experience with design systems and localization across multiple markets

• You understand conversion and think in journeys

• German at native level + good English

What we offer

• Competitive salary: €65,000–€90,000

• Equity - you’re building this, so you should own a piece of it.

• Food & drinks - lunch and dinner are on us at the Vienna office (plus all the drinks you want, and yes, we have protein bars and vitamins too).

• Relocation bonus (if you still need to move to Vienna)

• Equipment of your choice - whatever makes you happy.

• Regular team offsites.

Hiring process

• 15 min intro call

• 30 min skill interview

• 20 min culture fit with the founders
